Rebetzin- do you normally go to the bathrooom every half hour to check your sugar..i assume and hope not! so why should it be any different when your on a date? just be normal check your blood sugar before you leave the house (i mean before he comes) and then you should be fine..if you do feel yourself getting low and you dont wanna tell the boy just excuse yourself to the bathroom and eat a candy or something..its going to fine dont worry hashem will help you just like he helps everyone else!
